PRTG server security monitoring: What you’ll find on this page
PRTG makes server security monitoring as easy as it gets
Custom alerts and data visualization let you quickly identify and prevent cybersecurity issues.
Safeguard your server infrastructure from virtual and physical threats
Keeping your servers and data secure is critical for your organization to function. You need to ensure the confidentiality, integrity, and availability of all data and services across the organization. Paessler PRTG’s server security monitoring software is your 24/7/365 security detail for your entire IT infrastructure.
Identify unusually high traffic activity
Quickly identify potential network bottlenecks and unusual spikes in traffic. PRTG uses SNMP, packet sniffing, and flow protocols like NetFlow to detect suspicious activities that can indicate a security breach.
In the case of unusual or suspicious activity, PRTG helps you isolate servers or selectively disable applications for a targeted response.
Make integrity checks to sniff out danger
Set up PRTG to perform automated integrity checks of your files, folders, and logs. This way, you can uncover modifications to files or unusual log data that might otherwise be overlooked.
PRTG notifies you in case of any changes to your data that deviate from the norm, and alerts you via custom notifications so that you can react as quickly as possible to mitigate the potential threat.
Reduce network risks and complexity
Get a hold of your entire IT environment (on-premises or cloud-based) for robust security, including firewalls, anti-virus software, and other security measures.
With PRTG's network monitoring system, you can keep weak or even blind spots to a minimum by making sure that you have a 360° overview of all your systems and applications – all from a single dashboard.
Implement strong security mechanisms
Protect your servers and infrastructure against potential threats with physical security mechanisms. PRTG lets you keep an eye on electronic door locks or CCTV security cameras to prevent unauthorized access.
Even environmental parameters such as temperature and humidity can be monitored to protect your servers from hardware damage.
Start monitoring your server security with PRTG and see how it can make your network more reliable and your job easier.

5 reasons to choose PRTG as your server security monitoring tool
Monitor your entire IT infrastructure
PRTG monitors your entire network: servers, storage systems, connected devices (e.g., routers, switches, and printers), processors, RAM, fans, power supplies, traffic, and more.
With our all-in-one monitoring tool PRTG, you can eliminate the weak spots that tend to crop up when using multiple programs and reduce the complexity of your tech stack.
Monitor critical security points
Monitor a wide range of devices and systems crucial for server security. PRTG keeps an eye on firewalls, antivirus and backup software, file and log integrity, server health, unusual logins, open ports that can pose a threat, and more.
It also classifies network traffic and detects unusual activity between network components and behavior by device or user.
Monitor in real time, in the office, and on-the-go
When security threats arise, you need to know at once, whether you’re in the office, at home, or on vacation. PRTG server security continuously monitors your servers and hosts, alerting you even before there is a critical issue.
Our PRTG apps for iOS and Android give you the freedom to leave the server room with peace of mind, knowing that if there is no alert, everything’s running smoothly.
Get started with monitoring quickly
Server security systems, such as intrusion detection systems or trusted platform modules, can be complex and difficult to install on your network.
With PRTG, you can easily integrate such systems into your monitoring setup. PRTG itself is easy to install and configure, leaving sysadmins more time to focus on other IT tasks.
Proactive and quick to sound the alarm
PRTG ensures system failures are kept as short as possible – or prevented in advance.
Its built-in alarm system will send you an alert at the slightest sign of a problem, for example, if your firewalls or other security measures are about to crash or if a backup is faulty. This way, you can take action even before more serious problems arise.
Find the root cause of the problem with our PRTG server security monitoring solution
Real-time notifications mean faster troubleshooting so that you can act before more serious issues occur.
Your server security monitor at a glance – even on the go

Server security monitoring: FAQ
What is server security monitoring?
Server security monitoring is the continuous process of tracking, analyzing, and assessing the security of a server to ensure it is protected from unauthorized access, attacks, or other malicious activities. The goal of server security monitoring is to detect security incidents early, respond quickly, and prevent potential threats from compromising the server or the data it hosts.
Key aspects of server security monitoring include:
- Server management and monitoring: Monitoring different types of servers (cloud servers, physical servers, web servers, Linux servers, Windows operating system servers) in real-time to detect anomalies, unauthorized access attempts, and malicious activities. This often involves using server monitoring tools to check logs, network traffic, and system performance.
- Log analysis: Collecting and analyzing server log files (such as access logs, error logs, and system logs) to identify suspicious activities like failed login attempts, unusual patterns of access, or changes to files and configurations.
- Vulnerability scanning: Regularly scanning the server to identify potential vulnerabilities, such as outdated software, misconfigurations, or open ports that could be exploited by attackers.
- File integrity monitoring: Tracking changes to critical system files and configurations to ensure that unauthorized modifications have not occurred. This helps to detect malware or other forms of compromise.
- Access control and authentication monitoring: Keeping track of user login attempts, especially failed attempts or access from unusual locations, to detect brute force attacks or unauthorized access.
- Network traffic monitoring: Monitoring network traffic to and from the server, looking for unusual spikes, Distributed Denial of Service (DDoS) attacks, or unauthorized data exfiltration attempts.
Can PRTG scale with my server infrastructure?
Yes. Whether you have just a few servers or a gigantic server farm, PRTG adapts to the size of your server landscape. With PRTG’s powerful auto-discovery feature, even virtual servers are recognized automatically and incorporated into your monitoring environment.
Does PRTG replace antivirus software?
No. Antivirus software should always be installed to defend against viruses and other malware. However, PRTG can keep an eye on the availability and functionality of your antivirus software and thus ensure that it does its job.
Does PRTG server security include server room monitoring?
Yes. PRTG includes server room monitoring and helps you protect your server room from threats and damage due to unauthorized access or fluctuations in temperature and humidity. PRTG provides sensors that constantly monitor the health of your important servers and hardware, protecting your server room from power interruptions, malfunctioning air conditioners, smoke, and fire.
What is a sensor in PRTG?
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive.
On average, you need about 5-10 sensors per device or one sensor per switch port.
PRTG: The multi-tool for sysadmins
Adapt PRTG individually and dynamically to your needs and rely on a strong API:- HTTP API: Access monitoring data and manipulate monitoring objects via HTTP requests
- Custom sensors: Create your own PRTG sensors for customized monitoring
